BTS :Dance w/ the Devils (Vampire Slayer)

It is a Fanfict of a band in korea called Bts (BangTan Sonyeondan)

It is all about the war between the Vampire's And Demon's.
Vampire and Demon was the one who took after a book called Gimorie Book a book of black magic that can rule the world and any place that you want to be your's

But The Demon's cant' find that Book because of the 6 prince that was assign to find it.The prince's didnt took after that book because they just want is Play and have Games.

Then after so many years finally that prince's accept the assign task to them.Because finding that book has a Challenge to them

Then theres so many thing happen to them including Meeting a girl and fall in love w/ them.But before they become friends theres so many argument they do.

The Question is are they able to find the Book of Gimorie when they need to kill each others life???
